A followup:  Now that I know hardware flow control works, I dove back into the
documentation and actually found where the flow control parameters are documented.

In the Virtual Resource Manager Tech Reference (update by TNL 26 Sept 1986, my
latest version) Chapter 12, there is a discussion of the Asynchronous Device Driver.
In the discussion, the three valid entries of the 'pro' parameter are mentioned.
They are: 'dtr' - data terminal ready, 'cdstl' - connect data set to line, and
'dc' - direct connect.  There is more interesting information in this book.  However,
I wouldn't look in it as a normal course of events.  My initial reaction to the VRM
was, "That's an interesting way to achieve hardware independence".  But it looks like
some knowledge of the VRM is useful to those of us who are using the RT as a "UNIX box".

I'm fortunate that I had this book here. Originally, it had been ordered by mistake in
place of the AIX tech reference.  But I think you need them both.
